Indonesia - February 9th, 2012

This orthorectified wide-swath ASAR image shows several islands in Indonesia: (from left to right) Java (mainly East Java), Bali and Lombok. Also visible at the top are Madura (left) and Saubi (right).

East Java is a province of Indonesia. It is located on the eastern part of the island of Java and includes neighboring Madura and islands to its east (the Kangean and Sapudi groups) and to its north (Bawean and the Masalembu Islands). The provincial capital is Surabaya, the second largest city in Indonesia and a major industrial center and port.

Many volcanic peaks can be seen on the islands. One of the most prominent is Mount Rinjani, on Lombok, visible near the right edge. This active volcano on Lombok rises to 3726 m, making it the second highest volcano in Indonesia. On the top of the volcano is a 6 km by 8.5 km caldera, partially filled by Segara Anak (Child of the Sea) lake. This lake is approximately 2000 metres above sea level and estimated at 200 metres deep.

Indonesia - November 8th, 2011

This orthorectified wide-swath ASAR image shows Surabaya, located on the northern shore of eastern Java at the mouth of the Mas River and along the edge of the Madura Strait. It is Indonesia’s second-largest city, with a population of over 2.7 million (5.6 million in the metropolitan area), and the capital of the province of East Java.

Visible in the lower half of the image are numerous volcanic peaks, the most prominent of which are Iyang-Argapura (far right) and the Tengger Massif (due south of Surabaya). Iyang-Argapura is a massive volcanic complex that dominates the landscape between Mount Raung and Mount Lamongan in East Java. Valleys up to 1,000 m deep dissect the strongly eroded Iyang volcano.

The Tengger massif, also in East Java, includes Mount Bromo, an active volcano. At 2329 m it is not the highest peak of the massif, but is the most well known due to its activity and the fact that it sits in the middle of a vast plain called the “Sea of Sand”.
